    Senior Javascript Developer

    United States - Last active: 1 month ago - Tests: 1 - Portfolio: 1

    Right now my main interest would be in building 2D games using Unity, but I'd be interested in other game development opportunities as well. I have a very solid work ethic, and am used to working 10-20 hours/week on side-projects in the evenings. My latest side-project, NetPegs, was recently released for Amazon Fire TV, Google Nexus Player, and PC/Mac. By day, I am a senior Javascript developer with many years of professional development experience, both in the browser, and on the server. I have experience starting new projects from scratch, and also converting existing software from server-side platforms over to single-page Javascript apps. Although I love doing Javascript development, I get enough of that at work. In my free time, I'm most interested in making games.

    Hello, everybody! I realy addicted to programming. I like Web also. And I combine these two of my life interests with pleasure. If you'd like to create something interesting and quality in web-sphere then i'm sure we'd work together with maximum efficiency. I'm always ready to disscuss you problem and intend to solve it any way. Now I run a project - Busines portal of my native town. This site helps local enterpeneurs to advertise their sesrvices and goods to the potential customers. Site runs under WP CMS, but I digged the code to the bottom and there is no dark conners of the WP engine for me now. Duringn two years that site is under my management I studied HTML, CSS, JAVASCRIPT, PHP and MySQL sort of well. I achieved some succes in SEO also. I'm sure that today I'm able to solve a wide spectrum of problems that may occure in site construction/design/managing activities. So I will be very happy to share my experience to anyone who need it. Good luck everyone with your beginnings!
